"We want a merit-based program where people come into our country based on merit and we want to get rid of chain migration", Trump added, telling reporters that Saipov had been allowed to bring in 23 other people as a "primary point of contact".
"But when *you* say it, it makes it harder for DOJ (Department of Justice) to make that happen", wrote Andrew McCarthy, former Chief Assistant U.S. Attorney, on his personal Twitter account. He was shot in the abdomen by a police officer, arrested and taken to a New York City hospital.
"They should be forced to suffer and, when they kill, they should be executed for their crimes,"an excerpt from the ad read".
Also Thursday, Attorney General Jeff Sessions told members of law enforcement in NY in a visit scheduled before the attack that the US justice system can handle suspects like Saipov. In the United States, the application of death penalty is also plagued with arbitrariness, racial disparities, and error.
Authorities are trying to determine whether Sayfullo Saipov, who was charged Wednesday with providing support to a terrorist group, only drew inspiration from the Islamic State and its calls for adherents to attack using vehicles, or whether he was enabled in some way, which so far does not seem to be the case, officials said.
Putin holds talks with Iranian, Azerbaijani counterparts
Russian President Vladimir Putin exits his plane on arrival at Mehrabad airport in Tehran, Iran, Wednesday, Nov. 1, 2017. The two generals met in Tehran as part of efforts for expansion of military cooperation between the two countries.
CORRECTION: (Nov. 2, 8:30 a.m.): An earlier version of this article misstated the day when President Trump tweeted in support of the death penalty.
Tuesday's assault was the deadliest in New York City since September 11, 2001, when suicide hijackers crashed two jetliners into the World Trade Center, killing more than 2,600 people.
The president also called the USA criminal justice system as it applies to terrorism suspects "a joke" and "a laughingstock". A 23-year-old New York City man, a 32-year-old New Jersey man, five Argentinians and a Belgian national were among the eight people who died.
NY police officials say that the attacker appears to have self-radicalized and that it does not appear anyone else was involved, though they said that continues to be a key question in the worldwide investigation launched after the Halloween attack in Lower Manhattan killed eight people and wounded a dozen others.
"We're so politically correct that we're afraid to do anything", he said.
Trump also floated the idea of sending Saipov to the controversial Guantanamo Bay prison, which has been notorious for extra-judicial punishment, including torture.
